CONTROLLER FOR GAS-STOVES.

Specification of Letters Patent.

Application filed Kay 2, 1913. Serial No. 785,102.

America, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Controllers for Gas-Stoves, of which the following is a specification.

This invention relates to certain new and useful improvements in controllers for gas burners, and relates particularly to that type of controller orregulatpr which is adapted to be applied to the burner of a'gas or vapor stove, and which is operated through the medium of a vessel placed over the burner of such stove.

The invention has for its primary object to provide a controller of the above type which can be readily attached to any of the usual or ordinary gas stoves without necessitating any alteration of any of the parts of such stove.

The invention has for its further object to provide a device of the character described preferably so constructed that it may readily be adjusted to conform to different,

sized stoves.

A still further object of the invention is to provide a device of this type of extremely simple construction, which will not require the use of any special tools to applythe same to the burner, and which will be effective in use, and comparatively inexpensive to manufacture.

With the above and other objects in view, the invention resides in the novel construction, combination and arrangement of parts, as will be hereinafter more fully described and then claimed, and in describing the in vention in detail, reference will be had to the accompanying drawings forming a part of this specification, and wherein like numerals of reference will be employed to designate like parts throughout different views in which Figure 1 is a top plan view of a plurality of gas controllers constructed in accordance with the invention, the same being shown applied to the burners of a gas stove, the lat- Fig. 2 is a side elevation of the controller applied to .the burner of a gas stove, the burner being shown in dotted lines. Fig. 3 is a front or end elevation of the controller, one of the nipples of the valve casing being in cross section. Fig. 4 is a longitudinal sectional vlew through the .valve' casing of the con troller taken on the line 4-4 of Fig. 3. Fig. 5 is a detail view in side elevation of a modified form of operating lever. Fig.- 6 is a detach'ed detail view in side elevation of the controlling ,valve and, Figs. 7, 8, and 9 show modified forms or supporting clip or bracket.

It iscommonin all types of gas or vapor \stoves to employ a mixing tube which is located between the shut-off valve and the burner proper, and the present device is adapted to be readily attached to such mix- 1ng tube, and in connection therewith there is provided a controlling valve adapted to be operated by the mechanism hereinafter described.

In the accompanying illustration, 10 indica'tes the mixing tube of an ordinary gas stove which communicates with the burner 11, and is'provided at its outer end with an air mixer 12, the controlling valve being located between the mixer 12 and the supply line 14.

To apply the device, it is only necessary ply line 14 and substitute therefor the controlling valve shown in detail in' Figs. 4 and 6. This consists of a valve casing 15 having a nipple 16 for connection with the air mixer 12 and a nipple 17 for connection with the supply line 14. In this casing is a plug valve 18 provided with a suitable handle 19, and which plug valve has the usual transverse port 20. Inaddition tosaid port 20 Patented Apr. 21, 1914.

to remove the controlling valves on the supwhich communicates with a by-pass pipe 22 that is carried inwardly to the burner and terminates in a pilot light23 which may be of any suitable form, and which is disposed so as to ignite the gas at the burnerv 11.

The valve casing 15 is providedwith a valve seat 24 extending transversely, through the casing at right angles to thevalve 18, and in sald seat is a plug or other .form of rotary valve 25 which has a transverse port The stem of this valve projects to one side of the valve casing 15 and has suitably connected thereto one end ofa link 27, the

other end of which has a pin 28 to work in a slot 29'provided therefor in the operating lever 30. This operating lever is pivotally supported at 31 from a clip or bracket 32 which is hung on the mixing tube 10 and suit-ably secured in any desired manner by a set screw 33. The clip shown in the drawing is especially adapted for use in connection with the pivoted lever 30 being provided at one end with a curved arm 30 to embrace the tube upon which it is adjustably securedby the set screw 33, and at its oppositeend with parallel ears 30 between WillChtil lever is pivoted, as best shown in Figs. 7, 8, and-9. The'lever'comprises two sections, consisting of the main section 301 andaasupplemental or outer section 34 which is adjustably connected at by a set screw and slot with the outer end of lever 30. The making of this lever in two sections is for the purpose of providing a quick ad- 'justm'ent to adapt the device to difierent sized stoves.

. The lever at the outer end thereof is bent upwardly as best seen at 36 in Fig. 2 so that its free end will normally lie slightly above the plane of the burner 11, and this end may, if desired, be provided with a tripod 37 as shown in Fig. 5 of the drawings. The lever bracket for supporting the mixing tube are shown. In Fig. 7 the bracket 32' is exhibited as of J-forin, in Fig. 8, as of curvilinear rectangular form, and in Fig. 9, as of rightangled curvilinear contour. Either of these brackets will be effective for maintaining the mixing tube in operative position and may be substituted for that shown in Fig. 1.

With reference to the drawings, the device is shown in Fig. 2 with the gas shut ofi, and the operating lever in its normal position.

' When it is desired to use the stove, the valve 18 is turned by its handle 19 so as to allow the gas to pass from the supply pipe 14 through feed groove 21 and b'y-pass pipe 22 to the pilot light where it may he ignited. Upon placing a utensil over the burner 11,

the end 36 of the lever is depressed by the weightof such utensil, thus operating the link 27, opening valve 25, and turning the gas into the mixing tube 10 through which it passes to the burner 11 and is ignited by the pilot light. Obviously, further control of the gas ma be had by proper manipulation of the va ve 18. As soon as the utensil is moved from the burner, the counterweight 38 acts on the lever 30 so as to close valve'25, shutting off the flow of gas to the burner, but leaving the flow of gas through. by-pass pipe 22 to the pilot light uninterrupted until the valve 18 is closed by hand.

Particular attention is called to the fact that the device as shown and described may be readily attached to any of the ordinary forms of gas or vapor stoves, the application necessitating simply the removal of the usual valves found in the supply line 14 and the substitution therefor of the valve hereii shown and described.

I claim:

An attachment for gas ranges comprising a bracket secured to the gas feed pipe and having a curved arm and parallel ears, a. slotted lever pivoted between said ears, a counter-weight carried by the lever, the inner end of said lever having a longitudi nally adjustable extension, said extension having an upturned terminal arranged to be disposed Within a burner, a link having a pin projecting therefrom and entering the slot in the weighted end of the lever, a valve casing, a vertically-disposed shut-off valve therein provided with a curved feed groove. a by-pass communicating with the groove, and a horizontally -disposed controlling valve in said casing projecting at one side of the valve casing and having the other end of the link connected thereto for controlling the movement of the valve.

In testimony whereof I ailix my signature in presence of two witnesses.
